OutOfMemory - Sonar 无法分析项目源代码，也找不到问题

Question

我是运行插件 SonarLint，在 IntelliJ Idea 的 Java 项目中。

当我请求对整个项目进行代码分析时，我收到以下消息：

SonarLint 分析失败：Java 堆 space

这是日志：

如何增加内存？

Answer 1

Eclipse: Run --> Run Configurations --> 然后 select maven build 下的项目 --> 然后 select 选项卡 "JRE" --> 然后输入 -Xmx1024m.

Run --> Run Configurations --> select "JRE" 选项卡 --> 然后输入 -Xmx1024m

我建议你使用 profiler 来检查你需要多少内存，这样你就不会分配太多。

我错过了 IntelliJ Idea：

您可以获取信息here

请确保您在正确的位置增加了堆。您需要单击 IDEA 的 Ant 工具 window 中的 'Properties' 按钮并在那里编辑 'Maximum heap size (Mb)' 字段。
